SITE BACKGROUND


### U.S. Oil & 

### Refining Co. (USOR) was constructed in 1957 from units ofan old Spokane, Washingtontopping refinery, and consists oftwo parts: the refinery andtankfarm, and the marine terminal. The refinery houses the process units and the approximately 3- million barrel capacitytank farm on 122 acres. The marine terminal, where crude oil arrives andproducts are shipped out from two piers, lies approximately 3/4 mile northeast onthe Blair Waterway. Fourpipelines ranging indiameter from 8to 24 inches transmit crude oil andproducts betweenthe marine terminal andthe tank farm. Crude oil also arrives to a 60 railcar offloading station. Products are also loaded onto tankertrucks from the loading rack at the refinery and shipped viarail lines. USORhas the capacityto process 42,000 barrels per day ofcrude oil.

SITE INSPECTION


### Wastewater TreatmentSystem


### Process water and contaminated stormwater from the refineryreceive primary and secondarytreatment in a wastewatertreatment system onsite. After treatment, the water is discharged at Outfall 001Awhich flows into a City ofTacoma storm drain line. At 10:30 AM, the instantaneous flow, temperature, andpHfrom Outfall 001Awere 291 gallons perminute (gpm), 69.7 degrees Fahrenheit COF), and 7.94 standardunits (SU), respectively. The composite sampler containerhad atemperature of 1.0 degree Celsius (°C). These values were withinpermitlimits. Primarytreatment facilities for process wastewater include anAPI oil/water separator and aninduced air flotation (IAF) unit. All process wastewater and stormwaterrunoff from the process area is routedto the primary wastewatertreatment system. The treated water then goes to TankNo. 80008, whichprovides retention capacity and serves as an equalizationreservoir. Secondarytreatment facilities for process wastewater consist ofan activated sludge biological unit (Orbal) followed by a clarifier. The flow rate to the Orbal unit at 10:30 AMwas 299 gpm. Treated effluent is normallyroutedto Outfall 001A, however it canbe diverted to two wastewaterponds (also called offtestponds) during upset conditions. These ponds consist ofthe former equalizationpond and south offtest pond. During the inspection, we observed some scum onthe surface ofthe water inthe clarifier, which is considered normal operation. The effluent going overthe weir was clear with no color. The clarifier weirs are cleaned once a week during the summerto preventbuildup ofalgae. During winter months, USOR cleans the weirs as needed, typically about once permonth whenthe weather is cold and overcast.
Waste activated sludge from the clarifier is treated in an aerobic digester. Biosolids from the digester go throughtwo Somatpresses for dewatering. The dewatered biosolids are collected on a concrete pad thenremovedto the oily soil containment cell to be storedU.S. Oil & Refining Co. Page 3 of6 Class 2 Water Quality Inspection on April29, 2014


### until enoughbiosolids accumulate to be shippedto the LRI Landfill (Pierce County). Leachate from the pitinthe containment cell is returnedto the aerobic digester. All units ofthe system appearedto be working normally. Sanitary waste is collected and discharged separately into the City ofTacoma sewer system for treatment intheirmunicipal wastewater treatmentplant.
Stormwater Outfalls
Outfall 001B is a concrete structure usedto discharge stormwater, firewater, and hydrotest water. 

### Itis currently fitted with a temporary hose and discharge flows into the Lincoln Avenue ditch. The temporaryhose will be replaced with a hardpipe during the proposed Phase 4 ofUSOR's crude oil offloadingproject whichwill potentiallyinstall an additional48 railcar offload stations. The proposed Phase 4 crude oil offloading project is scheduled to be completedinNovember 2014.
Outfall 002 is locatednear Lincoln Avenue ditch onthe westportion ofthe facility. 

### Itis used to discharge stormwaterthat collects inthe tank containment areas and tank hydrotest water. Flowto this outfall is controlled by a manual valve. At the time of inspection, the tank containment area adjacentto the outfall hadno standing water.
Outfall 003 is usedto discharge stormwater from the Marine Terminal tank containment area. Stormwaterfrom the tank containment area drains to a vaultwhere the sampling point for Outfall 003 is located. Any oil present canbe retainedbybaffles inthe vault. The water inthe vault is thenpumpedto Outfall 003, an infiltrationbasin for release to groundwater. Areas withthe highest likelihood ofgenerating contaminated stormwater, such as pumppads or valve pads, drain to sumps which are pumped to a temporarytank thenpumpedto the refinery for treatment.
Outfall 004 is located inthe southernportion oftherefinery property, andusedto discharge storm water along Marshall Avenue. This natural drainage pointtakes stormwater from the eastern section ofthe refinery propertyto the ditch onthe north side ofMarshall Avenue, theninto the city's stormwater line.
Outfall 005 is an unlined, two-cell detentionpond facility with a flow control riser which is usedto mitigate stormwater flows during storm events. The samplingpointfor Outfall 005 is located at the end ofthe second detentionbasin. Afterthe stormwaterpasses over a weir at Outfall 005, apipe transports the stormwaterto Marshall Avenue which is approximately 350 feet east ofOutfall 004. Outfall 005 drains the newly improved facility siting areainthe southeastportion ofthe refineryproperty. Due to the flat geographic conditions ofthe site, the refinery constructed two pump stations to pump runoffgenerated byevents up to the 1 00-year 24-hour eventto the detentionpond facility. Ditches upstream ofthe pump stations provide temporary storage.
Outfall 006 is located on the Port ofTacomaRoad near an accessroadthat the refinery constructedto facilitate entrance to the newmaintenance building. The outfall serves aU.S. Oil & Refining Co. Page 4 of6 Class 2 Water Quality Inspection onApril29, 2014

### ® catch basin is usedto capture solids to.fulfill the water qualityrequirements ofthe 2008 Tacoma StormwaterManagementManual. USOR statedthat they replace the filters every 12 months.
None ofthe stormwater outfalls had flow during the inspection.

SAMPLING


### USOR staffretrievedthe 24-hour composite sample from Outfall 001A at 8:00AM on the morning ofthe inspection. Ecology splitthe composite sample inthe lab. Ecology also took a grab sample at Outfall 001A. USOR sampled for the sameparameters as Ecologyto compare results. Ecology sentthe wastewater samples to Manchester Laboratory for analysis. Ecology usedthe effluent flow atthe time ofthe inspectionto calculate pollutantmass loadings to Outfall 001A for the grab sample. The flow rate associated withthe Outfall 001A grab sample was 291 gpm (0.419 MGD). Ecology usedthe information submitted by USOR ontheir April2014 Discharge Monitoring Report (DMR) to determine the 24-hour effluent flow rate associated withthe Outfall 001A composite sample. The flow rate was 433.8 gpm (0.625 MGD).

LABORATORY 

### & RECORDS REVIEW


### Atthe laboratory, Mr. Sticka explained USOR's procedures andhelped Ecology with splitting the composite sample. USORrecords every sample from its collectionto its entry into the DMR. The composite sample is broughtto the lab andputinto a refrigerator at or below4

# oc until analyzed. Atthe time ofinspection, the refrigeratorwas at 2.72°C. Once samples are analyzed, the results are entered into a computer database. USOR also has a summary log book where all_testresults are entered. Datais crosscheckedbythe lab staffandto ensure its accuracy before itis entered onthe DMR.
The USORlaboratory is accredited for pH, TSS, BOD5, 

### COD, oil and grease, ammonia, andphenols. The accreditation expires November 30, 2014. USOR sends water samples to ALS Environmental in Kelso, Washington for analysis ofprioritypollutantmetals and NWTPH-Dx. USOR sends bioassay samples to the Nautilus Environmental Lab in San Diego, California. Bothlabs are accredited. Duplicates ofsamples are analyzed daily for TSS, COD, and oil and grease. BOD is analyzedtwice aweek, ammonia is analyzed once a week, and phenolics are analyzed every other month. Control charting is done for all parameters. Ecologyreviewedthe laboratory sampling results for May 6, 2013 and compared themto the May 2013 DMRsubmittedto Ecology byUSOR. The log book sheet for the specified day was complete, organized, and accurate.U.S. Oil & Refining Co. Page 5 of6 Class 2Water Quality Inspection on April29, 2014


### USOR'srecords are easily accessible and reflect the work being done.

RESULTS


### Table 1 summarizes Ecology's and USOR'sresults for the grab and composite samples and compares them to the currentpermit limits. The results showthatthe discharge during the sampling was withinpermit limits. USOR's sample analyses compared favorably with Ecology's.
